We report for the first time the occurrence of a maruyamaite (dravite with a high K content) + garnet + kyanite + biotite + muscovite + K-feldspar + quartz mineral assemblage in metamorphic rocks of the Barchi-Kol site (Kokchetav Massif). We estimate

The first data on the structure, textural features, and geochemical and mineral composition of Fe–Mn nodules of the Sasin Formation, Olkhon Island (Baikal), have been determined. A significant role in the formation of the nodules was played by hydr
